Technical Specifications

Inbound and outbound message handling
Sophos Email’s inbound and outbound filtering uses advanced detection methods across multiple languages:

• Reputation filtering for the majority of unwanted email prior to inspection
• Our anti-spam engine catches the rest, including the latest phishing attacks and malicious attachments – quarantining where required
• Methods such as ‘Sender Genotype,’ our next-generation reputation filtering technology, eliminate botnet spam at the IP connection level through monitoring
• Sophos Delay Queue provides protection against snowshoe spam, a preferred method of sending spam campaigns – Watch How it Works

Email Content Control Policies
Sophos Email Content Control policies make it easy to analyze email content and attachments for all inbound and outbound messages.

• Create multiple policies for groups and individual users
• Filter inbound and outbound messages for keywords and file types
• Identify specific keywords in email subject lines, message content, and file names
• Quarantine, delete, or strip attachments from email messages to prevent data leaks and malware threats

Block phishing imposters
Using a combination of authentication techniques, Sophos Email allows you to identify and allow legitimate emails from trusted partners and block imposters.

• Sender Policy Framework (SPF) to identify IP addresses authorized to send email from the domain – Watch How it Works
• Domain Keys Identified Mail (DKIM) provides cryptographic proof that a message was sent from a specific sender and hasn’t been tampered with
• Domain Message Authentication Reporting & Conformance (DMARC) determines what to do when messages fail SPF or DKIM checks from the sender
• Header anomaly detection to identify if the sender's display name is the same as one of your internal user names
